Oversize load permit in Spain (2026): authority, thresholds, fees

Key facts

Issuing authority

The authority depends on the territory: DGT for the AP-68 in Navarre and for the other roads outside the Basque Country, Navarre and Catalonia; Gobierno Vasco for the Basque Country; Gobierno de Navarra for Navarre (except the AP-68); Servei Català de Trànsit for Catalonia; municipalities for streets in towns. ACCs issued by the DGT after 1.05.2024 are not valid on roads in Catalonia. An ACC requires a favourable opinion from the road authorities along the route.

Application channel

TRAZA (DGT application for special authorisations — module 'Autorizaciones complementarias / Euromodulares'); journey notifications via the DGT to the Guardia Civil (ATGC) [Z1]

Login / access: User name and password for TRAZA ('Online — Usuario y contraseña — TRAZA'), granted on request (form 'Solicitud de acceso a la aplicación TRAZA'); in the form the application users give their NIF/NIE. How a person without a NIF/NIE obtains access was not verified.

Thresholds above which a permit is needed

Values for a typical combination: tractor unit with semi-trailer or rigid vehicle with trailer, 5 axles, standard width.

Values for a typical 5-axle combination (lowest value in the regulation); higher conditional limits only in these notes. An ACC is needed above the limits of anexo IX RGV (Z1, Z4). Width 2.55 m (2.60 m for insulated bodies). Height 4.00 m (4.50 m, among others, for vehicle transporters and intermodal containers). Length: motor vehicle and trailer 12.00 m; articulated vehicle 16.50 m; combination with a trailer 18.75 m; long elements (bars, beams, pipes) may project 1.50 m beyond the limit. Weight in the table = 42.00 t: 5-axle tren de carretera, 2-axle vehicle + 3-axle trailer (anexo IX, Z4) — the lowest value for a 5-axle combination; higher: vehículo articulado ≥ 5 axles (2+3 and 3+2) 44 t, tren de carretera 3+2/3+3 44 t (from 23.10.2025, Orden PJC/780/2025); +2 t in intermodal transport, +1/+2 t for alternative-fuel/zero-emission drive. Axle loads: single non-driven axle 10 t, drive axle 12 t (from 23.10.2025); semi-trailer tandem 11–20 t depending on spacing. The thresholds for domestic and international traffic are the same. A genérica-category ACC covers transports up to 20.55 × 3.00 × 4.50 m and 45 t (Z1). [Z4]

Permit types

Processing time

Maximum time limit for deciding and notifying the decision: 3 months from submission of the application. The time for opinions of the road authorities (who also have max. 3 months) and the time for completing the application are not counted. The vehicle may not set off before receiving the ACC. The official sources do not give a typical time in working days. [Z1]

Fees

Escort

Private escort vehicle

Escort vehicles (vehículos piloto) for group 1 (VERTE) depending on length, width, speed and road type: e.g. L ≤ 20.55 and A ≤ 3 at V < half the general speed — 1 escort vehicle behind; 20.55 < L ≤ 40 and/or 3 < A ≤ 5 — 1 escort vehicle (behind on motorways, in front on conventional roads; at low speed 2 on conventional roads); 40 < L ≤ 55 — 1 behind / 2 on conventional roads; L > 65 — 2 escort vehicles and Guardia Civil. On routes approved by the DGT, the police escort may be replaced by the 'auto-escolta' mode (2–3 escort vehicles; requires a feasibility study). The escort and the driver must have radio and telephone contact in a common language (anexo III RGC). [Z3]

Police escort

Escort by traffic agents (Guardia Civil ATGC or regional police) is mandatory at a width > 5 m (anexo III point 8 RGC) and in the cases in the DGT tables (e.g. 55 < L ≤ 65 on conventional roads, L > 65). The request for an escort or auto-escolta at least 72 h before the journey. Notification of the journey for a specific and exceptional ACC at least 24 h in advance to the ATGC of the province of departure (in the Basque Country / Catalonia / Navarre to the regional police) and to the road authorities; departure only after receiving the code (localizador) or after the time limit has passed without a reply. [Z3]

Required documents

• Application in TRAZA: applicant details (name, identification number, tax address), vehicles (registration, make, VIN, weights, dimensions, full axle characteristics, kingpin / drawbar, rear overhang), combination, load (type, description, name of the item, weights and dimensions), route (provinces, roads, sections) and the payment number of tasa 1.3 [Z1]
• Foreign vehicles: copy of the official technical document of the country of registration (equivalent of the ITV card) with the required data (axles, axle weights, dimensions, suspension, etc.); if the document does not contain the data — a technical certificate certified by an association of engineers or the manufacturer's original data sheet [Z1]
• Official translation into Spanish of all foreign-language documents by a sworn translator (Traductor-Intérprete Jurado MAEC); the originals are submitted physically at a JPT or by post to the DGT in Madrid (an electronic copy is not sufficient) [Z1]
• International transport, when the applicant is not entered in the Spanish register of hauliers: copy of the Community licence (or a bilateral / CEMT permit) with a sworn translation [Z1]
• Feasibility and safety study (estudio de viabilidad), signed by an authorised technician and certified by the professional association — when the weight is > 300 t, the load consists of several items (conjunto de elementos singulares), in auto-escolta mode or with a load overhang > 3 m [Z1]
• Vehicle rental agreement — when the applicant rents the vehicle from a rental company without a driver [Z1]
• In the vehicle: the ACC (printout of the electronically signed permit) and a sketch of the combination with axles, axle loads and dimensions (for combinations in special transport) [Z2]

Traffic restrictions

General and specific-category ACCs allow driving by day and by night; exceptional category — between sunset and sunrise only if the permit allows it (anexo III point 5 RGC). Max. speed: general 70 km/h, specific 60 km/h, exceptional according to the permit ≤ 60 km/h. In adverse conditions or with visibility < 150 m the vehicle must leave the carriageway. Minimum distance of 50 m from the vehicle in front. Each year the DGT sets traffic restrictions for periods of heavy traffic (TRAZA has a separate module for permits to drive during restriction periods) — the text of this year's resolution was not read.
